Joanna Forbes L’Estrange (b.1971) began composing and arranging as soprano and Musical Director of the five-time Grammy award-winning a cappella group The Swingle Singers. Her compositional style is influenced by a love of close harmony vocal groups and jazz. She has received commissions from The King’s Singers, The Military Wives Choirs, SingUp, Finchley Children’s Music Group, Aurora Nova and the National Youth Choirs of Great Britain as well as from choral societies, chamber choirs and schools. In collaboration with her husband Alexander L’Estrange, she writes songs (for their popular series of large-scale community choral works) and church anthems (recorded by Tenebrae on their On Eagles’ Wings CD); their set of carols for upper voices and piano, The Twyford Carols, is published by Faber Music. Joanna’s congregational setting of the mass, The St Helen’s Service, was published by the RSCM on International Women’s Day 2018.
